In dangerous operations, it is required to wear a protective helmet such as a fire helmet. In order to improve the safety of the fire helmet, it is necessary to improve the shock resistance of the fire helmet. Therefore, the present application discloses a fire helmet anti-shock mechanism, which is used to provide a device installed on the fire helmet to improve the anti-shock structure of the fire helmet.

[0003] According to patent publication number CN217885208U, a fire helmet with earthquake resistance function includes a helmet body, a fireproof transparent mask is installed on the front side of the helmet body, the helmet body is composed of three parts: an inner helmet, a middle helmet, and an outer helmet, a plurality of connecting rods are installed at equal distances between the inner helmet and the middle helmet, and a plurality of earthquake-resistant components are installed inside the helmet body, which aims to solve the problem that the shock absorption effect of old-style fire helmets is poor.

[0004] The above-mentioned device realizes shock absorption and buffering by installing multiple buffer springs in the fire helmet, and has a certain anti-vibration effect. However, during use, when the fire helmet is impacted, the buffer springs may shake and rebound, which may cause the wearer's head to shake, causing partial damage to the wearer's head. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies of the prior art, the utility model provides a fire helmet anti-vibration mechanism to solve the problem in the background art that the wearer's head may be injured by the spring anti-vibration.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire helmet anti-vibration mechanism, comprising: a fire helmet body; a buffer structure: the buffer structure is installed on the fire helmet body, and the shock resistance of the device is improved by the buffer structure; a protective structure: the protective structure is installed in the fire helmet body, and the user's head is protected by the protective structure.

[0009] By adopting the above technical solution, the fire helmet body is used for protection. After the fire helmet body is worn, the shock resistance of the device is improved by the buffer structure. When the device is shocked, the buffer structure is used to buffer the shock, thereby reducing the impact on the fire helmet body. The protective structure is in contact with the wearer's head, thereby reducing the direct impact on the wearer's head when the fire helmet body is shocked.

[0010] Optionally, the buffer structure includes two rotating rings, two support rods and an arc plate, two rotating shafts are fixedly connected to the fire helmet body, the two rotating rings are respectively rotatably connected to the two rotating shafts, the two support rods are respectively fixedly connected to the two rotating rings, the arc plate is fixedly connected to the two support rods, a plurality of rolling holes are opened on the arc plate, and balls are rotatably connected in the plurality of rolling holes.

[0011] By adopting the above technical solution, two rotating rings are supported by two rotating shafts, and the rotating rings rotate on the rotating shafts to drive the two support rods and the arc plate to rotate, so that the arc plate can be adjusted to a suitable angle so that it can face the impact position. When the shock wave reaches the arc plate, the fluctuation of the shock wave affects the ball bearings, causing the ball bearings to rotate in the rolling holes, thereby buffering the energy and reducing the subsequent impact force on the fire helmet body.

[0012] Optionally, limit plates are fixedly connected to both of the rotating shafts.

[0013] By adopting the above technical solution, the rotating ring is limited by two limiting plates to prevent the rotating ring from falling off the rotating shaft.

[0014] Optionally, the protective structure includes two fixing plates and a soft pad, the two fixing plates are fixedly connected to the fire helmet body, and the soft pad is fixedly connected to the fire helmet body.

[0015] By adopting the above technical solution, the two fixing plates and the soft pad are in direct contact with the wearer's head, so that the wearer's head can be isolated from the fire helmet body to avoid direct contact, so that the energy passing through the fire helmet body can be buffered, reducing the impact on the head.

[0016] Optionally, two anti-slip pads are fixedly connected to the two fixing plates.

[0017] By adopting the above technical solution, the shaking of the helmet when the wearer wears the fire helmet body is reduced by using four anti-slip pads.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a fire helmet anti-vibration mechanism, which has the following beneficial effects:

[0020] The anti-vibration mechanism of the fire helmet protects the wearer's head through the fire helmet body. After the wearer is put on, the support rod and the arc plate are driven to rotate by rotating the rotating ring on the rotating shaft, so that the arc plate is adjusted to a suitable angle. When impacted, the shock wave first contacts with a plurality of balls, causing the balls to roll irregularly in the corresponding rolling holes, thereby buffering the energy. The wearer's head is isolated from the fire helmet body by two fixing plates and a soft cushion to avoid direct contact, and when subsequent energy reaches the fire helmet body, the impact on the head is reduced. The device buffers the impact on the fire helmet body in advance through a structure installed on the outside of the fire helmet body, thereby reducing the shaking and impact on the wearer's head caused by installation in the helmet.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] See also Figures 1 to 4, a fire helmet anti-seismic mechanism, comprising: a fire helmet body 1; a buffer structure: the buffer structure is installed on the fire helmet body 1, and the shock resistance of the device is improved by the buffer structure; a protective structure: the protective structure is installed in the fire helmet body 1, and the user's head is protected by the protective structure. After the fire helmet body 1 is worn, the shock resistance of the device is improved by the buffer structure. When the device is shocked, the buffer structure is used to buffer and reduce the impact on the fire helmet body 1. The protective structure contacts the wearer's head to reduce the direct impact on the wearer's head when the fire helmet body 1 is shocked. The buffer structure comprises two rotating rings 2, two support rods 3 and an arc plate 4. Two rotating shafts 5 are fixedly connected to the fire helmet body 1. The two rotating rings 2 are respectively rotatably connected to the two rotating shafts 5. The two support rods 3 are respectively fixedly connected to the two rotating rings 2. The arc plate 4 is fixedly connected to the two support rods 3. A plurality of rolling holes are opened on the arc plate 4. Balls 6 are rotatably connected in the plurality of rolling holes. The two rotating rings 2 are supported by the two rotating shafts 5. The rotating ring 2 rotates on the rotating shaft 5 to drive the two support rods 3 and the arc plate 4 to rotate, so that the arc plate 4 can be adjusted to a suitable angle so that it can face the impact position. When the shock wave reaches the arc plate 4, the fluctuation of the shock wave affects the ball 6, causing the ball 6 to rotate in the rolling hole, thereby buffering the energy and reducing the subsequent impact force on the fire helmet body 1. The two rotating shafts 5 are fixedly connected to the limiting plates 7. The two limiting plates 7 are used to limit the rotating ring 2 to prevent the rotating ring 2 from falling off the rotating shaft 5, thereby protecting the fire helmet body 1. The structure includes two fixing plates 8 and a soft pad 9. The two fixing plates 8 are fixedly connected in the fire helmet body 1. The soft pad 9 is fixedly connected in the fire helmet body 1. The two fixing plates 8 and the soft pad 9 are in direct contact with the wearer's head, so that the wearer's head can be isolated from the fire helmet body 1 to avoid direct contact, so that the energy passing through the fire helmet body 1 can be buffered and the impact on the head is reduced. Two anti-slip pads 10 are fixedly connected to the two fixing plates 8. The four anti-slip pads 10 reduce the shaking of the helmet when the wearer wears the fire helmet body 1.

[0028] To sum up, the working principle and working process of the anti-seismic mechanism of the fire helmet are as follows: when in use, the device is moved to a suitable position, and the wearer's head is protected by the fire helmet body 1. After wearing, the support rod 3 and the arc plate 4 are driven to rotate by rotating the rotating ring 2 on the rotating shaft 5, so that the arc plate 4 is adjusted to a suitable angle. When impacted, the shock wave first contacts with multiple balls 6, causing the balls 6 to roll irregularly in the corresponding rolling holes, thereby buffering the energy. The wearer's head is isolated from the fire helmet body 1 by two fixed plates 8 and a soft pad 9 to avoid direct contact. When subsequent energy reaches the fire helmet body 1, the impact on the head is reduced.

[0029] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
